Door-fastening

DOOR-FASTENING.

SPECIFICATION forming part of Itetters'Patent No. 248,365, dated October 18, 1881.

Application filed April 12, 1881.- (No model.)

To all whom it may concern:

Be it known that I, BENJAMIN F. STULTZ, a citizen of the United States, residing at White Pigeon, in the county of St. Joseph, State of Michigan, have invented a new and useful Improvement in Door-Fastenings, which improvenient is fully set forth in thefollowing specification and accompanying drawings, in which- Figure l is a view of doors having my invention applied to them. Fig. 2 is a horizontal section on line a; fr, Fig. l.

Similar letters ot' reference indicate corresponding parts in the several figures.

My invention relates to improvements in fasteners for barn-doors, &c formed of bolts and an operating-lever.

lhe invention consists of a block or plate secured to the door at the portion between the inner ends of the two bolts, which are pivoted to the operatinglever, whereby the motions of said bolts are limited and the pivots of the bolts and lever relieved of strain, as will he hereinafter fully set forth.

Referring to the drawings, A represents the door or doors of a barn or other building or object.

B represents a horizontally-arranged lever, which is pivoted to the door at or about the center of the outer end thereof, and C represents two verl ically-arranged fastening bars or bolts, which -arepivoted to the lever B on opposite sides ofthe pivotal boltD of the lever, one of the bolts extending upwardly and the other downwardly, and each passing through an eye or guide, E, respectively at the top and bottom of the door, and having its end'adapted to engage with a keeper or openingin the relative portion of the dor-frame, each bar or bolt being formed of a single piece of rigid material.

F represents a block or plate, which is secured to the door in such position that the pivotal bolt D passes through it, and is therefore between the inner ends of the bolts C, said block or plate extending vertically, and being of such length that it projects above and below the horizontally-arranged lever B.

When the door is closed and requires fastening, the leverB is lowered. This shoots the two bolts C in opposite direction into the keepers or openings of the door-frame, thus simultaneously fastening the top and bottom of the door. In order to open the door the lever B is raised, whereby the two bolts leave the keepers or openin gs of the door-frame and the opening of the door may be accomplished. It will be seen that in either movement of the bolts C their inner ends abut against the block or plate F, and thus limit the motions of the bolts, the operation of the lever being immediately stopped. Furthermore, said abutments F relieve the pivotal bolt D of the lever B and the connecting pivotal bolts D of the fasteningbolts C of any strain otherwise occasioned, if the motion ofthe bolts C were unlimited, and thus loosening or displacement of said bolts D D and fracture of the lever B and fasteningbolts C is prevented.

The fastening-bolts extend at an angle or are inclined, so that the outer ends of the bolts may enter the top and bottom keepers or openings at coincident places in the door-frame and as far removed as possible from the hinges of the door, or as near as possible to the outer edge of the door, the guides E being arranged relatively to the inclination of the bolts, thus preventing warping of the door at both its upper and lower ends.

The bars or bolts C are each formed of a rigid piece or a single unbroken length of ma.- terial, and may thereby be operated with positive motions, springs and rollers being dispensed with, and said motions are accomplished with ease and facility. Furthermore, said bolts C, the hand-lever B, and eyes or guides E may be made of wood, thus providing a cheap and inexpensive fastening applicable to a single door, or fastenings applicable to double doors independent of each other, so that if one door is opened the other door may remain fastened, as desired, and will not slam.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The bolts() and lever B,in combination with the abutment block or plate F, limiting the motion of the bolts and relieving the pivots of strain, substantially as and for the purpose set forth. B. F. STULTZ.
